Description:
Abstract:
This project installed seepage meters to measure the volume of groundwater seepage into the overlying marine environment. The water will be analyzed for major nutrient levels. The data from this project include the site and values of seepage flux.
Purpose:
The Florida Keys contain 25,000 septic tank systems, approximately 5000 cesspools, and 1000 class 5 injection wells. Depth of injection wells ranges from 10 to 30 meters. Excessive algal growth, coral diseases, and both marine grass and sponge lortality is perceived to be caused by sewage nutrients leaking from roundwater on both sides of the Florida Keys. Determining the volume and composition of groundwaters seeping into the marine environment from teh sea floor is vital to management decisions on the area.

The objective of this study was to determine the volume and composition of groundwaters seeping upward through the rock water interface into Florida Bay and the coral reef tract. Submarine groundwater input into Florida Bay has been ignored by modelers and results show current models are likely to be erroneous. An additional major product will be an improved seepage meter design.

Process_Description:
For the seepage meter experiment in south Florida (Florida Bay, Florida Keys) a new design of seepage meters was developed. A fiberglass mold (approx. 70 cm x 70 cm) was constructed from an off-the-shelf household skylight. Approximately 60 seepage meter domes were constructed and installed at various locations throughout the study region. Because the study region's underlying Pleistocene limestone is very heterogeneous, several domes were installed in certain locations to combat hydrologic variations which control flow in and out of the subsurface. The fiberglass seepage meter provided a rigid frame which was them mounted to the bare rock seafloor throughout Florida Bay and along the Keys. Portland cement was mixed and used to seal the edges of the fiberglass domes. A hole was previously cut in the dome top to be used for connecting a plastic bag. The preferred bag was a turkey basting bag because of its construction material.

After the domes were in place and the cement had cured, basting bags were placed on the domes. The bags were left on the dome for a 24 hour period (one tidal cycle) and subsequently removed. The volume on the bag was measured with a calibrated graduated cylinder. Knowing the volume over the 24 hour period and the area of the seepage meter, a flux (L/m2/d) could be calculated. These measurements were recorded and placed in spreadsheets to determine variations by location and other environmental factors (i. e., rain, tide, wave).
